Some rocks in this area are on private property. Property owner requests signed waiver. MORE INFO >>>

The remainder are on US Forest Service land. A map detailing the public areas can be obtained from the ranger station en route to the rocks from the village of Tres Piedras. According to Jan Studebaker: "The property line runs from approximately the current east corner by the access gate in a straight line over the top of South Rock to the top middle of the Chicken Heads/Mosaic Wall mount, and from there west down the mount slope to the meadow just south of the Alley climbs. Some of the most popular routes are completely on private property. There are survey markers on the top of South rock (the mysterious aluminum stake stuck in the rock) and on top of the Mosaic rock (most of the time buried in water in a pot hole.)"

A new online Tres Piedras Route Guide from LA Mountaineers has been updated with the latest access information, and should be read by all Tres Piedras climbers. Group climb leaders, and Climbing Directors (future or past) should take particular note. From the guide:

Access Notes: Tres Piedras climbers should sign the waiver found on this page because the popular South Rock is mostly on private land, as is some of the access to the area. The landowner, requests a waiver, NO fires, no chalk and "please close any gates".

In order to nurture greater landowner acceptance of climbers, participants of group climbs are requested to organize quick clean up activities before leaving the area; this should include the climbing area as well as the access roads (trip leaders could supply plastic grocery bags). Small parties should practice "leave no trace" principles.

On August 19, 2009 the landowner stated: "Yes I still own the property, and yes I'd still like to have waivers on hand - even or perhaps especially from your organization. Only once in awhile do I have problems with climbers, mostly not picking up after themselves. My biggest gripe is that despite repeated requests, the climbers don't remove protection (edit: colored webbing, shiny hardware) from the climbing routes, which is both lazy and unattractive. Your organization could do me a big favor by doing a group climb and removing the crap that others have left on the various routes so that it is both a pristine part of the landscape, and so that each climber must figure out his own route without relying on the handiwork of others."

Description

The hardest easiest-looking climb I've ever seen. Originally rated 10d, now listed at 11a in the books, and harder if you're short.

The first bolt is clipped with a reachy undercling (stickclip or find a tall friend if <5'9"). Step right of this bolt, grab the "juggy" crystals and move up to the horizontal crack using footholds under the low overlap that you can't see (1st crux). If you're too short, this move might not be protected because you might not be able to reach the bolt. Traverse left 10' along the horizontal overlap. Up past the rest of the bolts with a distinct high-step/mantle move (crux), with a bolt at your nose for the crux move. After the last bolt, run it out on 5.6 to the anchor (shared with Thunder Toad).

Danger Mouse is the greatest secret agent in the world, and would certainly climb this with no difficulty.

This is an excellent climb for a person looking to try their first 5.10+/11- at TP. The bolts are right where you want them.
